I was looking forward to the movie because of the actors/actresses and the plot, but I was very disappointed. The plot and the subject of artificial intelligence have a potential that is not reflected in the film (they should have made a series of at least 12 episodes)..Artificial intelligence is neither fantasy nor science fiction, it is the current and future reality of the world (personally I am afraid of artificial intelligence and not because I not technologically but from the dangers inherent in it if it reaches destructive governmental and private entities).
The plot was very confusing at first. (Less in the second part, but the film still suffers from many plot flaws) such as a lack of understanding of processes, which also resulted in the waste of talented actors who barely had screen time..

As for the soundtrack...the truth is I don't even remember maybe because my mind was busy analyzing the confused plot

*** And just for general knowledge, the actress Tang Wei (Chinese) is married to Kim Tae Yong who is the screenwriter and producer of the film
